Repeating earthquakes, or repeaters, are identical in location and geometry but occur at different times. They appear to represent recurring seismic energy release from distinct structures such as slip on a fault patch. ... Repeating earthquakes are observed in diverse tectonic and nontectonic settings.
Vacuole: is a cavity in the cytoplasm of a cell that contains inorganic or organic material such as fluid, food, or waste.
lysosome: are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
Mitochondria: is the "powerhouse" of the cell. They take in nutrients, break it down, and creates energy rich molecules for the cell.
cell membrane: protects the cell from its surroundings. It consists of a layer of lipid bilayer with embedded proteins.
I really hope this helps:)
Answer:
This question have two parts.
Question 1. Is a 0.185 M aqueous solution of sodium sulfate, Na2SO4, hypertonic, hypotonic or isotonic to red blood cells?
Answer:
Hypotonic because sodium sulfate is a detergent which can cross the lipid bi-layer.
Question 2. If normal red blood cells were suspended in this Na2SO4 solution, what would be the expected outcome?
Answer:
Hemolysis (Bursting of Red blood cells) will occur due to excessive movement of water inside the cell resulting from sodium sulfate solution.
